TaxDome is the other gravitational mass in US practice management. Unlike Karbon, TaxDome is bootstrapped (no outside investors by public disclosure), headquartered in New York, and sits at 15,000+ firms in 25+ countries by the company's own 2024 annual report. G2 and the 2025 CPA Practice Advisor Readers' Choice Award have both placed it at the top of the tax-practice-management category, and its 2026 "Accounting Industry Index" — an internal dataset from its 15,000-firm base — reported 22% average client-base growth across US TaxDome customers in 2025.
Where Karbon leans toward workflow and communication, TaxDome leans toward compliance workflow: e-signature, secure client portal, engagement letters, document request lists ("organizers"), and bills-and-payments live inside one product rather than a constellation of tools. For a small-to-mid US tax practice that bills by the return and wants an all-in-one, TaxDome is the highest-conviction pick in this index. The counter-argument is exactly that concentration — if the firm outgrows a vertically integrated stack, the migration cost is meaningful.
AI features (document tagging, draft responses, workflow suggestions) are rolling in steadily but are not the product's centre of gravity. US local fit is the highest in the firm cohort; UK presence is real but secondary to IRIS and Karbon there.
